@arena posts LMArena WebDev Arena Rankings leaderboard

A leaderboard of 11 models posted on July 28, 2025 drew 107K views and a 0.66% engagement rate.

What happened

@arena posted a WebDev Arena Rankings leaderboard on July 28, 2025. It was the account's only post that day.

The numbers

It reached 107K views, ranking #370 of 1,162 AI chart posts and #72 of 239 @arena posts. The median for AI chart posts is 39.9K views.

The lesson

The leaderboard drew 107K views, 2.3x the 46.2K median for @arena posts, but its 0.66% engagement rate sits below the AI chart median. Wide reach with thin engagement is what the numbers show for this chart type.

What it means

At #70 of 239 @arena posts by score, this leaderboard trails most of the account's own chart posts despite its 107K views. The 0.66% engagement rate against 107K views marks the gap between reach and response.
